The Switch Manager tool is also intended for MiCOM Px4x IEDs with redundant Ethernet using Self Healing Protocol
(SHP) and Dual Homing Protocol (DHP). This tool is used to identify IEDs and Alstom Switches, and to configure the
redundancy IP address for the Alstom proprietary Self Healing Protocol and Dual Homing Protocol.
Switch hardware
Alstom switches are stand-alone devices (H3xx, H6x families) or embedded in a computer device rack, for example
MiCOM C264 (SWDxxx, SWRxxx, SWUxxx Ethernet boards) or PC board (MiCOM H14x, MiCOM H15x, MiCOM H16x).
Switch range
There are 3 types of Alstom switches:
Standard switches: SWU (in C264), H14x (PCI), H34x, H6x
●
Redundant Ring switches: SWR (in C264), H15x (PCI), H35x,
●
Redundant Dual Homing switches: SWD (in C264), H16x (PCI), H36x
●
Switch Manager allows you to allocate an IP addresses for Alstom switches. Switches can then be synchronized
using the Simple Network Time Protocol (SNTP) or they can be administrated using the Simple Network
Management Protocol (SNMP).
All switches have a single 6-byte MAC address.
Redundancy Management
Standard Ethernet does not support a loop at the OSI link layer (layer 2 of the 7 layer model). A mesh topology
cannot be created using a standard Hub and switch. Redundancy needs separate networks using hardware in
routers or software in dedicated switches using STP (Spanning Tree Protocol). However, this redundancy
mechanism is too slow for one link failure in electrical automation networks.
Alstom has developed its own Redundancy ring and star mechanisms using two specific Ethernet ports of the
redundant switches. This redundancy works between Alstom switches of the same type. The two redundant
Ethernet connections between Alstom switches create one private redundant Ethernet LAN.
The Ethernet ports dedicated to the redundancy are optical Ethernet ports. The Alstom redundancy mechanism
uses a single specific address for each Ethernet switch of the private LAN. This address is set using DIP switches or
jumpers.
Switch Manager monitors the redundant address of the switches and the link topology between switches.

INSTALLATION

Switch Manager requirements
PC with Windows XP or later
●
● Ethernet port
200 MB hard disk space
●
PC IP address configured in Windows in same IP range as switch
●
Network IP address
IP addressing is needed for time synchronization of Alstom switches and for SNMP management.
Switch Manager is used to define IP addresses of Alstom switches. These addresses must be in the range of the
system IP, depending on the IP mask of the engineering PC for substation maintenance.
Alstom switches have a default multicast so the 3rd word of the IP address is always 254.
Installation procedure
Run Setup.exe and follow the on-screen instructions.
